Training Heart Rate Monitor About Heart Rate Zones Many athletes are using heart rate zones to measure and increase their cardiovascular strength and improve their level of fitness. A heart rate zone is a set range of heartbeats per minute. The five commonly accepted heart rate zones are numbered from 1 to 5 according to increasing intensity. Generally, heart rate zones are calculated based on percentages of your maximum heart rate. Fitness Goals Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying these principles: • Your heart rate is a good measure of exercise intensity. • Training in certain heart rate zones can help you improve  cardiovascular capacity and strength. • Knowing your heart rate zones can prevent you from overtraining and can decrease your risk of injury. If you know your maximum heart rate, you can use the table (page 9) to determine the best heart rate zone for your fitness objectives. If you do not know your maximum heart rate, use one of the calculators available on the Internet. Some gyms and health centers can provide a test that measures maximum heart rate.
